Title: Improvements in and relating to electric sockets
IPC: H01R33/46
Filed: 1959-07-14
Abstract: 890,260. Two-part couplings; lamp-holders. COMPAGNIE GENERALE D'ELECTRICITE. July 14, 1959 [Aug. 4, 1958; Dec. 12, 1958], No. 24123/59. Class 38 (1). A lamp-holder which cannot be taken to pieces comprises a base 10 formed with an inwardly directed flange 11 which holds in place an insulating member 22 and the outwardly directed flange of a casing 4. Sufficient play is left so that the base can be turned in relation to the member 22 and so secured to a support. Holes 17, 18 in the casing 4 give access to fixing screws 15, 16, in terminals 8, 9 fitted in the member 22. Serrations 19, 20 on the member 22 and the base 10 face each other and lock together when the member 22 is pressed against the base, e.g. when a lamp is inserted in the socket, and prevent relative rotation between these parts. In another embodiment, Figs. 5 to 10 (not shown), the base is formed with fixing tags which engage notches in the casing to prevent relative rotation.

Patent GB-592161-A (GB)
Title: Improvements in or relating to apparatus for dividing high frequency power
IPC: H01P5/12
Filed: 1943-07-23
Abstract: 592,161. Coil -- less resonators. SPERRY GYROSCOPE CO., Inc. July 23, 1943, No. 24309/45. Convention date, Feb. 4, 1942. Divided out of 592,119. [Class 40 (iii)] [Also in Group XXXVI] Apparatus having broad frequency band characteristics is arranged so as to, effect energy division in a concentric line. As shown in Fig. 1, two hollow end conductors 25, 26 are held a fixed distance apart by a member 27 and terminated by tapered concentric line adaptors 28, 28<1> adapted to receive concentric transmission line terminals. A central member 29 is slidably mounted between the two end members 25, 26 and can be fixed in adjusted position by a screw 30 slidable in a slot in the member 27. The inner conductor of the central member 29 has a varying diameter, whilst the outer conductor is of constant diameter. The central member 29 is provided with a high impedance tap 34 at its lowest impedance point, where the inner conductor has a sudden reduction in diameter, corresponding to an increase in impedance. The tap 34 has attached to it an outer conductor 54 of constant inner diameter and an inner conductor 53 of slowly increasing diameter, so that at the point 55 the impedance of the line is equal to that of the line to be attached. In order to allow for the effect of standing waves due to energy reflections, the position of the tap between the two fixed end sections 25, 26 is varied so as to obtain maximum and minimum readings from which the actual energy transfer along the transmission line may be determined. In order to minimize end reflections due to wall thickness at a sliding joint in a concentric line, the tube end may be cut at an angle as shown at 32, Fig. 2, or may be terminated in a helix 32<1>, Fig. 3. Alternatively, the ends of the sliding tubes exposed to the travelling waves may be staggered by a distance equal to a quarter wavelength as described in Specification 581,972. In the alternative form of current or energy dividing device shown in Fig. 4, energy to be divided is introduced into the tapered matching end 59 and is divided into calculable portions at the tap 341. The portion tapped by the branch 49<1> is fed to a device for measurement or other purposes whilst the remainder travels into a terminating impedance 36, which may be of carbon, graphite, or other semi-conductor. The unused energy is entirely absorbed and no reflection can occur to cause a standing wave at the tap 34<1>, which may therefore be fixed. In a modification, Fig. 5, the inner conductor is stepped at 62, 63, 64, 65, 67, 68, 69 and the inner conductor of the branch is stepped at 66, 67, 72, 73. The steps are such that the change in the logarithm of the impedance at each step is proportional to the corresponding binomial coefficient of order one less than the number of steps. Two or more of the current dividing devices shown in Figs. 1, 4 or 5 may be used in cascade. The outer conductor may vary in diameter.

Title: Improvements relating to pick-up tube arrangements
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N9/09
Filed: 1963-08-31
Abstract: 1,093,806. Television; cathode-ray tube circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 28, 1964 [Aug. 31, 1963], No. 34506/63. Headings H4F and H4T. The beam current in a camera tube 1 (e.g. an image orthicon or lead oxide, photoconductive type) which is employed for generating a high definition luminance signal Y is restricted so as to obtain the highest resolution or to limit noise. This introduces a disadvantage however in that the current is insufficient to discharge the target for high lights, particularly those in excess of the selected value for peak white for which the beam current is normally chosen to be just adequate. In accordance with the invention this disadvantage is overcome by controlling the beam current or its discharge effect in accordance with a low definition video signal derived from at least one further camera tube. In one way of carrying out the invention the beam current is controlled by a low definition signal derived from cameras 2, 3 and 4 (e.g. vidicon or lead oxide, photoconductive type) which produce colour signals R, G and B. The signals are combined in a resistor network 5, 6 and 7 and may be gamma corrected, reference being made to the production of an equi-energy brightness signal and luminance signals of the kind having individual and overall gamma correction. After amplification at 8 and levelling in a circuit 9 the signal is applied through a circuit 10 to control the beam current in tube 1. Circuit 10 is an amplitude discriminator and may be set to pass signals exceeding peak white or a selected value below this level. If desired, circuit 10 may be dispensed with and the signal from circuit 9 applied to control tube 1 continuously. Reference is made to the use of a signal store, e.g. a storage tube, to permit repeated control of tube 1 in successive fields from an excess signal derived in one field. As an alternative to controlling the beam current intensity in tube 1, the discharge effect may be controlled by controlling the potential of the target relative to the cathode. The signal from circuit 10 may also control the gain of an amplifier for the tube signal. In another way of carrying out the invention, Fig. 2 (not shown), the signal from the colour cameras are applied via a diode selector circuit which passes the maximum signal in excess of peak white at any instant. It is stated that the invention may be applied to a monochrome camera by the addition of a further low definition pick-up tube.

Title: Process for decolorising heavy spar
IPC: C09C1/02
Filed: 1931-09-01
Abstract: A process of decolorizing heavy spar without any leaching operations comprises heating it in an oxidizing atmosphere, for example, at 900-1300 DEG  C. with the addition of small quantities, say 0,5-1 per cent, of oxides or other oxygen-containing compounds, such as of potassium, aluminium, magnesium, zinc or zirconium.  The added substances need not necessarily be devoid of colour.  Thus, alkali sulphate coloured yellow by iron, coloured unrefined alums, sulphates of potassium, sodium, magnesium or mixtures thereof, gypsum of a yellowish or brownish tinge, unrefined yellowish zinc oxide, or natural zincite may be used. Sodium or potassium carbonate or nitrate, sodium silicate and zinc sulphate are also specified.  The decolorizing action is stated to be due to formation of silicates of the colouring elements, and if insufficient silica is present in the heavy spar, free or combined silica, such as waterglass, is added prior to calcination.  The material may be heated directly by an oxidizing flame, preferably with agitation, as in a rotating drum, or the presence of excess oxygen may be attained by incorporating in the charge small amounts of substances evolving oxygen, such as an alkali nitrate or peroxide.  The addition may be added to the preferably crushed spar in solid form, or in solution.

Abstract: 643,434. Energy and quantity meters. SANGAMO WESTON, Ltd. Sept. 20, 1948, No. 24624. [Class 37] An. electric current to be integrated with respect to time is applied at t1, t2, Fig. 1, to energize winding M which causes pointer P to move at a speed proportional to the applied current ; the pointer oscillates between contacts Cl, C2 to actuate relay A which changes over the contacts a2, a3 to reverse the current through M and actuates a counter at contacts a5; according to the invention, electromagnetic means reinforce. the contact pressure between P and C1, C2, the electromagnetic means being energized in unison with the reversal of the current through M. As shown in Fig. 1, windings B1, B2 act as electromagnets to attract P and are energized sequentially by relay A ; relay A is actuated when P contacts C1 and released when P contacts C2, so that the counter is operated once for an oscillation of P from C2 to C1 to C2. As shown in Fig. 2, pointer P is moved by winding M1 and when contact is made with x or y, winding M2 is energized in the appropriate direction to urge pointer P towards the contact ; relays A or B are thus energized to actuate the counter D and to energize or de-energize relay C which reverses the contacts c4, c5, and operates contacts c1, c2 to locate the circuit of winding M2. Finally, as shown in Fig. 3, when contact P reaches x or y, the resistance R3 is put in circuit to add to .the current through M1 and thus reinforce the contact pressure; resistance R3 is removed from circuit at C2 or C1 when relay C is actuated or released. In both Figs. 2 and 3, the counter is operated for each swing of P from x to y or y to x. Specifications 538,160 and 629,716 are referred to.

Abstract: 979, 019. Centralized position-indicating arrangement; testing counters. STANDARD TELEPHONES & CABLES Ltd. June 21,1963 [June 28, 1962], No. 24880/62. Headings G4A and G4F. [Also in Division H3] A co-ordinate display arrangement comprises a display panel with x rows and y columns of display positioning so that any one of xy possible positions of a mobile unit in an area may be displayed; a number of stores, each of which can be allocated to a mobile unit, for storing data relating to the position of an associated mobile unit so that the data stored selects one of the xy positions; and means for applying pulses to the stores sequentially to render the associated xy intersection effective to display the position of the appropriate mobile unit. An aircraft control display comprises a number of column of lamps representing 2 degrees steps in longitude from 10 degrees W to 40 degrees W and two "pending " columns P for receiving details of aircraft approaching from the east and west. The columns are arranged to give 24 rows which correspond to three lanes at eight heights between 28, 000 ft. and 41, 000 ft. The panel also includes a section 1 at the top for giving an indication of the time at which the aircraft crossed the last marked meridian, and its estimated time at the next. The bottom of the panel 2 is provided with a number of identification keys and indicators, one for each aircraft plotted up to a total of thirty. Assume an aircraft approaching from the west is to be plotted, then an unoccupied store is selected, and data relating to its position altitude, lane and aspect is fed into the store from a control panel Fig. 4 (not shown) and sets the position of a number of uniselectors, and energizes the appropriate "pending lamp at the right hand side of the display panel. The position shows an arrow pointing to the left and may be horizontal or tilted up or down depending on whether the aircraft is flying level or climbing or diving. When the aircraft passes the 10 degrees W meridian fresh data is fed into the store and the indicator takes up a new position corresponding to the new data. These positions also show vertical bars as well as the arrows which indicate whether the aircraft is in the first or second half of a two degree interval of longitude. The arrival time, at this meridian and the estimated arrival at the next are also fed in to the store, and the display automatically steps on to the next position at the appropriate time giving a flashing "overdue" signal until a fresh report is received from the aircraft to be fed to the store. A pulse generator produces short high intensity pulses which sequentially selects each store and its associated display position, the repetition rate of the pulse being high enough to give a steady light on the display panel at each position which is energized. The pulses are derived from a binary counter Fig. 7 which provides two additional outputs used for checking the counter operating speed, by means of a cup and bucket counter Fig. 8.
